vertex remove in mesh

[fa furrukh]

I wanna delete all vertex at once , how can I do this ..

Just select the ridge (not the entire mesh).

The mesh will highlight but only the ridge nodes will show.

Then just delete.

You will be left with nodes on the boundary of the mesh that you will have to move to delete.

ThankYou !

This technique still leaves nodes where the deleted ridge crossed the perimeter of the mesh object. There can still be a lot of work to do, node by node, if you have deleted several ridges (maybe because it's time to replace existing topography with designed topography). I want a quicker cleaner path for this work.
